Interstate is now on the Costco GC2 label.
GC2 spec
bulk: 14.4V
absorption: 15.3V
float: 13.2V
equalization: 15.6V
What's interesting is that bulk and absorption are not equal. It appears they want to limit max current during bulk.
When battery voltage gets to 14.4 and to end Bulk, you hold voltage there so amps taper, howinheck can you get the amps to keep tapering when you jack voltage to 15.3 for Vabs?
It would go back to constant current till battery voltage reaches 15.3 and then start tapering again from there.
The Vector profile gets the battery to 14v, then amps taper but voltage keeps slowly rising till by the end of Absorption it finally reaches 14.8. That taper start at 14v is programmed in the charger so Stage 2 Absorption is not with constant voltage, but more of a controlled voltage you could call it.
